Laboratory Performance in the Palm of Your Hand

The YSA-P400 series combines handheld field portability with laboratory-oriented spectrum analysis specifications. It covers 9 kHz up to 40 GHz with a Displayed Average Noise Level (DANL) of -161 dBm/Hz and phase noise performance of -107.5 dBc/Hz at 1 GHz (10 kHz offset).

The YSA-P400 features a fully integrated Real-Time Spectrum Analyzer (RTSA) architecture with 100 MHz bandwidth, fixed-LO IQ capture, transient and burst analysis, spectrum probability density, real-time spectrogram, and record/playback tools. This makes it suitable for 5G network maintenance, radar testing, interference hunting, and wireless monitoring workflows.

Why Handheld?

Traditional benchtop spectrum analyzers deliver excellent performance but are often heavy and bulky, limiting their field deployment capabilities. The YSA-P400 changes the equation:

  • Only 1.5 kg - carry it to any site, any rooftop, any mast
  • 3 hours of battery life - no mains power required
  • External power bank supported - extend operation in the field
  • 10.1-inch IPS multi-touch display - intuitive gesture control, no external monitor needed
  • 40 GHz coverage - supports field RF analysis up to 40 GHz
  • -161 dBm/Hz DANL - laboratory-grade sensitivity in a portable form factor

Typical Applications

  • 5G Network Maintenance
  • RF Interference Hunting & Spectrum Monitoring
  • Radar Testing
  • EMC Pre-compliance Testing
  • Wireless Monitoring
  • Scientific Research & Education

YSA-P400 Active Directional Antenna Accessories

Pair the YSA-P400 with the XDA-1000 / XDA-2000 active directional antennas for directional signal search, interference hunting, field-strength workflows, and attitude-aware GNSS mapping from 500 MHz to 10 GHz or 20 GHz.

Key Advantages

  • DANL -161 dBm/Hz at 1GHz
  • Real-time 100 MHz analysis bandwidth with transient and burst analysis
  • Display 10.1" multi-touch touchscreen
  • Integration USB data interfaces and USB-to-serial connection
  • Connectivity USB 3.0 (Type-C), USB 2.0 (Type-C & Type-A), Micro HDMI

Performance Highlights

  • Frequency 9 kHz to 40 GHz
  • DANL -161 dBm/Hz
  • Real-Time BW Up to 100 MHz
  • Form Factor Handheld
